Im using this phone from past 11 months .after buying this phone I was happy because j7 works efforlessly but after 11 months its starts hanging I deleted many apps to clear the phone memory but the hanging problem continued.now currently im using this phone and a new problem arise that is as I turn the brightness to the lowest the lower middle screen starts blinking nt the whole screen bt only the lower screen. I see many of the j7 in which this problem is occurring even the new 2016 phone . So I recommend all the buyer only to purchase this phone when this problem gets eliminated.
